In this Feb. 9, 2016, file photo, United Nations High Commissioner for Human Rights Zeid Ra’ad al-Hussein speaks in Colombo, Sri Lanka. The U.N. human rights chief said on Wednesday, Oct. 12, 2016, that U.S. presidential candidate Donald Trump would be "dangerous from an international point of view" if he is elected.

U.N. human rights officials, whose boss famously likened U.S. President-elect Donald Trump to ISIS, are reported to be gearing up for a four- or even eight-year battle with the new administration over Trump's "ghastly campaign pledges," NBC News reported.

With Trump now elected president, the U.N. high commissioner for human rights, Zeid Ra'ad al-Hussein, has spread the word to the U.N. human rights office that it will have to lead international opposition to the United States, U.N. officials told the respected journal Foreign Policy.

"We are going to speak up," Foreign Policy quoted one of the officials as saying in an article published Tuesday. "It'll be rough, but if [Trump] puts any of those ghastly campaign pledges into action, we will condemn."

This is not the first time Ra'ad al-Hussein spoke out against Trump. "If Donald Trump is elected, on the basis of what he has said already, and unless that changes, I think it's without any doubt that he would be dangerous from an international point of view," he said in October.
